[0001] The utility model relates to water gas mixing device technical field, specifically, relate to a kind of gas mixer and beverage machine. BACKGROUND

[0002] Carbonated beverage, also known as soda, is a soft drink made by charging carbon dioxide gas into water. In the production process, the key step is to effectively blend carbon dioxide with water to produce carbonated water. Currently, there is a gas mixer on the market, which works by introducing carbon dioxide gas and water into a static soda mixing chamber. In this closed space, carbon dioxide dissolves in water and is converted into carbonic acid. Subsequently, after being treated by flow guiding and passive pressurization, the carbonated liquid is discharged for use.

[0003] However, this static mixing method has a significant defect: after carbon dioxide and water are introduced into the mixing chamber, their mixing effect is not ideal, and carbon dioxide gas is difficult to fully dissolve in the water, resulting in the quality of the output soda mixture failing to meet the expected standard, thereby affecting the taste of carbonated beverages. SUMMARY

At the same time, the gas (mainly carbon dioxide) is sent into the tank through the air inlet, and due to the formation of water mist, the contact area of water and gas is greatly increased, so that the gas can be more effectively dissolved in water to generate carbonic acid.

[0015] The gas mixing machine forms water mist by high-pressure water flow impacting on the torrent plate, greatly increases the contact area of water and gas, thereby improves the dissolution efficiency of carbon dioxide in water, and compared with the traditional static mixing mode, can significantly improve the mixing effect, so that the output of the soda mixture is higher and closer to the expected standard.

Moreover, although the cold water system is increased, the overall structure of the beverage machine still maintains compactness, the connection and layout between components are reasonable, and it is convenient for user to operate and maintain.

[0028] It should be noted that the modification of "one" or "multiple" mentioned in the present application is illustrative and not limiting, and those skilled in the art should understand that unless otherwise explicitly indicated in the context, it should be understood as "one or more".

[0029] As Figure 1 , Figure 2 , Figure 3As shown in the figure, the present invention provides a gas mixer, comprising: a tank body 1, a water inlet and an air inlet on the tank body 1, a water inlet pipe 2 at the water inlet, one end of the water inlet pipe 2 extending into the tank body 1 through the water inlet, and a sealing cap 21 connected to the end of the water inlet pipe 2 inside the tank body 1, the sealing cap 21 having a water inlet hole 211, and a jet plate 22 below the water inlet hole 211, the jet plate 22 being used for impacting the high-pressure water jet sprayed through the water inlet hole 211 to splash and form water mist, so as to fully mix with the gas sent into the tank body 1 through the air inlet.

[0030] Specifically, when high-pressure water is injected into tank 1 through inlet 211, it directly impacts the atomizing plate 22. This high-speed water impact causes water to splash up, forming a fine water mist. Simultaneously, carbon dioxide gas is introduced into tank 1 through inlet. Due to the significantly increased surface area of ​​the water mist, the carbon dioxide gas can more fully contact and dissolve in the water mist, thus generating carbonated water. This method of promoting gas dissolution through physical means (i.e., water impact forming water mist) significantly improves the dissolution efficiency of carbon dioxide compared to static mixing. To ensure the height and high pressure of the water jet ejected through the outlet to form a fully atomized water body, the pressure of carbon dioxide injected into tank 1, the volume of water injected into tank 1, the diameter of inlet 211, and the height of atomizing plate 22 from inlet 211 must be controlled according to the volume of tank 1 to ensure that the water jet impacting atomizing plate 22 fully forms a water mist. The turbulence plate 22 is located below the water inlet hole 211. The turbulence plate 22 covers the area of ​​the water inlet hole 211 projected onto the turbulence plate 22, ensuring that the water jet from the water inlet hole 211 can impact the turbulence plate 22. At the same time, the turbulence plate 22 has sufficient structural strength to ensure that it will not be easily damaged during the impact of the water flow.

[0031] In this embodiment, the high-pressure water jet impacting the agitator 22 creates a water mist, significantly increasing the contact area between water and carbon dioxide gas. This improves the dissolution rate and solubility of carbon dioxide, resulting in a carbonated beverage mixture that better meets expected standards and enhances its taste. The mixer in this embodiment avoids the use of high-speed rotating or vibrating components, making it more stable during operation, reducing failure rates and maintenance needs. Furthermore, its simple structure makes it easy to manufacture and maintain, contributing to lower production and maintenance costs. Moreover, the mixer in this embodiment fully utilizes the kinetic energy of the water flow to enhance the mixing effect, requiring no additional energy consumption and aligning with energy conservation and environmental protection principles.

[0032] Optionally, such as Figure 3 As shown, the turbulence plate 22 is connected to the sealing cover 21 via a connecting rod 23. One end of the connecting rod 23 is connected to the outer peripheral wall of the turbulence plate 22, and the other end of the connecting rod 23 is connected to the outer peripheral wall of the sealing cover 21.

[0033] Specifically, when the high-pressure water flow is sprayed onto the torrent plate 22 through the water inlet hole 211, the torrent plate 22 needs to withstand the impact force of the water flow and remain stable to ensure that the water mist can be uniformly and effectively formed and mixed with the carbon dioxide gas. If the torrent plate 22 is not fixed stably or is not in the right position, it may cause the water flow to splash unevenly, affecting the mixing effect. By connecting the torrent plate 22 and the sealing cover 21 through the connecting rod 23, the position of the torrent plate 22 in the tank body 1 can be ensured to be stable and not easy to shake or deviate. At the same time, the connecting rod 23 also plays a role in supporting and fixing the torrent plate 22, so that it can withstand the impact force of the water flow without deformation or damage. The connecting rod 23 can be made of metal or plastic, etc. with sufficient strength and rigidity to withstand the impact force of the water flow. At the same time, the length and diameter of the connecting rod 23 can also be adjusted according to actual needs to ensure that the connection between the torrent plate 22 and the sealing cover 21 is stable and not easy to loosen.

[0034] In this optional embodiment, the torrent plate 22 is fixedly connected with the sealing cover 21 through the connecting rod 23, one end of the connecting rod 23 is connected with the sealing cover 21, and the other end is fixed with the torrent plate 22, which ensures the stability and position accuracy of the torrent plate 22 in the tank body 1. The fixed position and stability of the torrent plate 22 enable the high-pressure water flow to uniformly impact the torrent plate 22, forming a more delicate and uniformly distributed water mist, thereby improving the mixing efficiency of the gas and water. The connecting rod 23 makes the connection between the torrent plate 22 and the sealing cover 21 simpler, facilitating installation, disassembly and maintenance, and reducing the maintenance cost of the equipment.

[0035] Optionally, as shown in Figure 3 , the torrent plate 22 is located directly below the water inlet hole 211, and the torrent plate 22 covers the area where the water inlet hole 211 projects on the torrent plate 22.

[0036] In this optional embodiment, the area where the water inlet hole 211 projects on the torrent plate 22 is located in the central region of the torrent plate 22, ensuring that the water flow sprayed through the water inlet hole 211 can impact the torrent plate 22 to form a water mist.

[0037] Optionally, as shown in Figure 1 , Figure 2 , a water level sensor 3 is connected to the tank body 1, one end of the water level sensor 3 extends into the tank body 1 to detect the water level in the tank body 1, and the other end of the water inlet pipe 2 is provided with a first control valve, and the water level sensor 3 is electrically connected with the first control valve.

[0038] Specifically, one end of the water level sensor 3 extends into the tank body 1 to detect the water level in the tank body 1 in real time. The water level sensor 3 transmits the detected water level signal to the first control valve. The first control valve automatically adjusts the opening and closing state of the water inlet pipe 2 according to the signal of the water level sensor 3. When the water level in the tank body 1 is below the set value, the first control valve opens to allow water to enter the tank body 1 through the water inlet pipe 2. When the water level in the tank body 1 reaches the set value, the first control valve closes to stop water from entering, preventing the water level from being too high and overflowing the tank body 1.

[0039] In this optional embodiment, the water level in the tank body 1 is automatically adjusted through the cooperation of the water level sensor 3 and the first control valve, avoiding the tediousness and errors of manual operation. Automation reduces human intervention, allowing the gas mixer to operate continuously and stably, improving production efficiency. The water level sensor 3 monitors the water level in real time, ensuring that the water level in the tank body 1 is always within a reasonable range, avoiding overflow due to high water level or poor mixing due to low water level. By precisely controlling the water level, water waste is avoided, and equipment damage caused by abnormal water level is reduced, reducing the risk of equipment failure or safety accidents caused by abnormal water level.

[0040] Optionally, as shown in Figure 4 The gas inlet is connected to a gas inlet pipe 4 to introduce gas into the tank body 1. The gas inlet pipe 4 is provided with a pressure regulating device 41 at one end outside the tank body 1 to control the gas pressure entering the tank body 1.

[0041] Specifically, one side of the tank body 1 is provided with a gas storage tank for storing carbon dioxide gas. The gas storage tank is connected to the gas inlet pipe 4 through a pipeline, and a pressure regulating device 41 is provided at the outlet end of the gas storage tank. The pressure regulating device 41 includes a second control valve and a pump body. When gas needs to be introduced into the tank body 1, the second control valve is first opened to allow gas to enter the tank body 1 through the gas inlet pipe 4. The opening degree (or flow area) of the second control valve can be adjusted to control the flow and pressure of the gas entering the tank body 1 through the gas inlet pipe 4. As the gas continuously enters the tank body 1, the gas pressure in the tank body 1 gradually rises. By precisely adjusting the opening degree of the second control valve, precise control of the gas pressure in the tank body 1 can be achieved. Through the pressure regulating device 41, the gas mixer can accurately adjust the gas pressure in the tank body 1 according to different working conditions and application requirements. For example, when smaller and more uniform bubbles are needed, the gas pressure in the tank body 1 can be appropriately increased; when energy consumption needs to be reduced or equipment failure needs to be avoided, the gas pressure in the tank body 1 can be appropriately reduced.

[0042] In this optional embodiment, the pressure regulating device 41 can accurately control the pressure of the gas entering the tank 1. By precisely controlling the gas pressure, the mixing process of the gas and liquid (such as water) can be optimized, thereby improving the mixing efficiency, generating more uniform and smaller gas bubbles, and enhancing the contact area and mixing uniformity of the gas and liquid. The pressure regulating device 41 enables the gas mixer to adapt to different working conditions and application requirements. For example, under different gas pressures, the gas mixer can adjust the opening of the pressure regulating device 41 to maintain the optimal working state. By precisely controlling the gas pressure, equipment failures or safety hazards caused by excessively high or low pressure can be prevented, ensuring the long-term stable operation of the gas mixer.

[0043] Optionally, as shown in Figure 1 The tank 1 is provided with an exhaust port, and an exhaust pipe 5 is connected to the exhaust port. The exhaust pipe 5 is connected to a safety valve at one end outside the tank 1.

[0044] Specifically, the safety valve is set to a specific opening pressure. When the gas pressure in the tank 1 exceeds this set value (for example, when the pressure regulating device 41 fails), the valve disc of the safety valve will be pushed open, opening the exhaust port, thereby allowing the gas to be rapidly discharged through the safety valve to the external environment through the exhaust pipe 5, to rapidly release the excess gas in the tank 1, thereby preventing safety accidents such as rupture or explosion of the tank 1 due to excessive pressure. At the same time, when the gas pressure in the tank 1 decreases below the safety level, the safety valve will automatically close to maintain the sealing of the tank 1.

[0045] In this optional embodiment, the safety valve improves the safety of the gas mixer and can rapidly respond when the gas pressure in the tank 1 abnormally increases, releasing excess gas, thereby effectively preventing safety accidents. By timely releasing the excess gas in the tank 1, the safety valve can prevent the tank 1 from being damaged due to excessive pressure, prolonging the service life of the equipment.

[0046] Optionally, as shown in Figure 1 The tank 1 is provided with a water outlet, and a water outlet pipe 6 is connected to the water outlet to output the mixed liquid outside the tank 1. The water outlet pipe 6 is connected to a pressure relief valve 61 at one side outside the tank 1.

[0047] Specifically, after the gas and liquid (such as water) in the tank 1 have been mixed for a period of time, the desired mixed liquid (such as carbonated water) is formed. At this time, in order to take out the mixed liquid from the tank 1, the water outlet needs to be opened (possibly through a certain control mechanism, such as a valve) to allow the liquid to flow out. The mixed liquid is then guided to the outside of the tank 1 through the water outlet pipe 6 connected to the water outlet for subsequent use or processing. When taking out the mixed soda water from the water outlet pipe 6, the water pipe is first depressurized through the pressure relief valve 61, so that the pressure range of the soda water flowing out through the water outlet pipe 6 is appropriate.

[0048] In this optional embodiment, the water outlet and the water outlet pipe 6 are arranged to enable the mixed liquid to be continuously and stably output from the tank 1, meeting the demand for continuous production in practical applications. The pressure relief valve 61 releases the excessive pressure in the water outlet pipe 6 in time, so that the liquid with appropriate pressure range flows out of the water outlet pipe 6, facilitating the subsequent use, and avoiding the high-pressure and rapid water flow at the water outlet pipe 6, which is inconvenient for people to use.

[0049] Optionally, as shown in Figure 5 The tank 1 is sleeved with a cold water tank 7 outside, the cold water tank 7 is provided with an evaporator 71, and the cold water tank 7 is provided with a water suction pipe 72, and the water suction pipe 72 and the water inlet pipe 2 are connected with a water pump 73.

[0050] Specifically, when the ice carbonated beverage is needed to be made, the evaporator 71 is used to make the water in the cold water tank 7 into cold water, and then the water pump 73 sends the cold water in the cold water tank 7 into the tank 1 through the water suction pipe 72 and the water inlet pipe 2, and the cold water enters the tank 1 of the gas mixer and mixes with the carbon dioxide gas to make the ice carbonated beverage for the user to use.

[0051] In this optional embodiment, the cold water tank 7 and the evaporator 71 are provided to provide cold water for the tank 1, so that the ice carbonated beverage can be made according to the needs, meeting more diversified consumer demands, and reducing the temperature in the tank 1 helps to improve the solubility of the gas, thereby producing higher quality products.

[0052] Optionally, as shown in Figure 5 The cold water tank 7 is provided with a compressor 74, a condenser 75 and an expansion valve 76 outside, the compressor 74 is connected with the condenser 75 through a pipeline, the condenser 75 is connected with the evaporator 71 through a pipeline through the expansion valve 76, the evaporator 71 is connected with the compressor 74 through a pipeline, and one side of the condenser 75 is provided with a cooling fan 77.

[0053] Specifically, the outer side of the cold water tank 7 integrates a complete refrigeration cycle system, which is composed of four core components of a compressor 74, a condenser 75, an expansion valve 76 and an evaporator 71, and is tightly connected through pipelines to form a closed refrigeration circuit. The compressor 74 serves as the power source of the refrigeration cycle system, compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas, and then the high-temperature and high-pressure gas enters the condenser 75 to exchange heat with the cooling medium in the condenser 75. In order to accelerate the heat dissipation process of the condenser 75, a heat dissipation fan 77 is also arranged on one side of the condenser 75. When the heat dissipation fan 77 works, it can accelerate the air flow around the condenser 75, thereby improving the heat dissipation efficiency. The refrigerant gas after heat dissipation of the condenser 75 condenses into high-pressure liquid, and when the high-pressure liquid passes through the expansion valve 76, throttling occurs, the pressure rapidly decreases and partially vaporizes to form low-temperature and low-pressure wet steam, which then enters the evaporator 71. The wet steam absorbs heat in the cold water tank 7 and evaporates in the evaporator 71 to cool the water in the cold water tank 7. The evaporated refrigerant gas is again sucked into the compressor 74 to start the next refrigeration cycle.

[0054] In this optional embodiment, through the cooperative work of the compressor 74, the condenser 75, the expansion valve 76 and the evaporator 71, the refrigeration cycle system can efficiently reduce the water temperature in the cold water tank 7 to the required level to meet the cooling demand of the gas mixing machine.

[0056] Specifically, the beverage machine is a multifunctional beverage device integrating the aerator and the cold water tank 7, and the machine body 8 is used as the support and protection structure of the whole device, and the aerator and the cold water tank 7 are ingeniously integrated together. On the surface of the machine body 8, two beverage outlets are arranged, i.e. the cold water outlet 81 and the soda outlet 82. The aerator is arranged in the machine body 8, and the water outlet pipe 6 of the aerator is connected with the soda outlet 82 of the machine body 8 in a close manner. When the aerator works, the generated soda will flow into the soda outlet 82 through the water outlet pipe 6, and then be taken by the user. The cold water tank 7 is provided with a cold water pipe 78, and one end of the cold water pipe 78 is connected with the cold water outlet 81 of the machine body 8 in a communicating manner. The cold water tank 7 is internally provided with a refrigeration cycle system (such as the compressor 74, the condenser 75, the expansion valve 76 and the evaporator 71) for reducing the water temperature to a required level. When the user selects to drink cold water, the cold water in the cold water tank 7 will flow out to the cold water outlet 81 through the cold water pipe 78, and then be taken by the user. When the user needs to drink ice carbonated beverage, the cold water in the cold water tank 7 can be sent into the tank body 1, and then the cold water will enter the tank body 1 of the aerator to mix with the carbon dioxide gas, so as to produce the ice carbonated beverage for the user.

[0057] In the optional embodiment, the beverage machine integrates the aerator and the cold water tank 7, and provides two beverage choices of cold water and soda, so as to meet the needs of different users.

[0058] Although the utility model discloses as above, the protection scope of the utility model is not limited to this only. The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will all fall into the protection scope of the utility model.
